missing ; before statement jquery error

I get this error that I don't understand:

`missing ; before statement`

Here is the code

        },
        'addevent' : function(data, formData){
            var entry = fx.deserialize(formData); 
        }, 
        'deserialize' : function(str){
            var data = str.split("&"),

            pairs = [], entry开发者_C百科{}, key, val; //ERROR

The syntax

entry{}

doesn't look right to me.

Do you want entry={},

Have it in one line:

var data = str.split("&"), pairs = [], entry{}, key, val;

You are missing = sign, should be:

..., entry = {}, ...

},
        'addevent' : function(data, formData){
            var entry = fx.deserialize(formData); 
        }, 
        'deserialize' : function(str){
            var data = str.split("&");

            pairs = [];
            entry = {key, val};

        var data = str.split("&"), <====== Here should be ';'

        !var! pairs = [], entry{}, key, val; //ERROR // var should be again
